[0011] As a further optimization, in order to improve the friction of the front wall of the sliding handle and facilitate the sliding of the slider along the second strip-shaped through hole by pushing the front wall of the sliding handle, the front wall of the sliding handle is uniformly provided with longitudinal grooves along the length direction.

[0012] As a further optimization, in order to guide the airflow and allow it to pass through the heat dissipation and dustproof net more smoothly, thereby improving heat dissipation efficiency, a wind guide baffle structure is fixedly connected to the upper end of the rear wall of the net cover, and its lower end extends to the lower end of the rear wall of the net cover.

[0013] As a further optimization, to facilitate the disassembly and installation of the strip plate, inclined plate, and longitudinal baffle, the air guide baffle structure includes: The screw is uniformly and fixedly assembled to the upper end of the rear wall of the mesh cover along its length; A strip plate, which has a pre-drilled hole corresponding to the screw; The screw is threaded with an internal threaded sleeve after passing through the corresponding reserved hole; The lower end of the strip plate is bent to form an inclined plate, which is inclined toward the side away from the mesh cover; The lower end of the inclined plate is bent to form a longitudinal baffle, which covers the area below the rear wall of the mesh cover.

[0015] This utility model provides an improved, easily detachable heat dissipation and dustproof mesh for photovoltaic power generation, which has the following improvements and advantages compared with the prior art: During the assembly of the heat dissipation and dustproof components, the relatively long plug-in positioning structure is first connected to the outer edge of the heat dissipation window for positioning, allowing for easy disassembly and positioning of the left end of the heat dissipation and dustproof components. Subsequently, the right end of the heat dissipation and dustproof components is positioned for easy disassembly and positioning through the easy-to-disassemble limiting and fixing structure.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0022] Please see Figure 1-7 This utility model provides a technical solution: a detachable heat dissipation and dustproof net for photovoltaic power generation, comprising: The photovoltaic box inverter unit 1 has a heat dissipation window 2 at the upper back of its back; The heat dissipation window 2 is equipped with a detachable heat dissipation and dustproof component 3, which includes: A shield 31 is provided to shield the outside of the heat dissipation window 2. A sliding auxiliary positioning structure 35 is installed between the upper and lower sides of the shield 31 and the outer edge of the heat dissipation window 2; A plug-in positioning structure 32 is installed between the left side of the shield 31 and the outer edge of the heat dissipation window 2; A removable limiting and fixing structure 34 is installed between the right side of the shield 31 and the outer edge of the heat dissipation window 2. The front wall of the shield 31 is evenly provided with fish-scale heat dissipation holes 37; A mesh cover 33 is snapped onto the rear edge of the shield 31, and a filler filter cotton 36 is inserted inside it.

[0023] Specifically, in this embodiment, the photovoltaic box inverter integrated machine 1 and the heat dissipation window 2 opened on it are both existing technologies; Furthermore, during the assembly of the heat dissipation and dustproof component 3, the relatively long plug-in positioning structure 32 is first connected to the outer edge of the heat dissipation window 2 for positioning, and the left end of the heat dissipation and dustproof component 3 is positioned for easy disassembly; then the right end of the heat dissipation and dustproof component 3 is positioned for easy disassembly through the easy-to-disassemble limiting and fixing structure 34; finally, the upper and lower sliding auxiliary positioning structures 35 are used to position the upper and lower sides of the heat dissipation and dustproof component 3 to the outer wall edge of the heat dissipation window 2 for easy disassembly, which improves the stability after assembly. All three positioning structures adopt connection structures that are easy to install and disassemble, without the need for external tools, which is more convenient to disassemble compared to the traditional fixing method with more bolts. More specifically, the front end of the shield 31 has fish scale heat dissipation holes 3 for heat dissipation and ventilation. The fish scale heat dissipation holes 3 can reduce the entry of dust. The filled filter cotton 36 allows for ventilation while blocking dust. Understandably, the front end of the mesh cover 33 is snapped onto the rear edge of the shield cover 31, and can be disassembled when needed to replace the internal filling filter cotton 36, making it convenient to use.

[0024] In some embodiments, the insertion positioning structure 32 includes: The first ear plate 321 is fixedly assembled to the rear edge of the left side of the shield 31; A positioning plug is fixedly connected to the middle of the rear wall of the first ear plate 321; A positioning hole 322 is provided at the outer edge of the heat dissipation window 2 corresponding to the positioning plug, and the positioning plug is inserted into the positioning hole 322; The positioning plug includes: The insert plate 323 has elastic metal sheets 324 integrally formed on the upper edges of its left and right side walls; A gap is left between the elastic metal sheet 324 and the outer wall of the insert plate 323; The outer wall of the elastic metal sheet 324 is engaged with the positioning hole 322.

[0025] Specifically in this embodiment, the positioning plug is inserted into the positioning socket 322 and positioned by friction, connecting the left end of the heat dissipation and dustproof component 3 and the outer edge of the heat dissipation window 2. Applying external force to this connection can pull the positioning plug out of the positioning socket 322 for easy disassembly. Furthermore, the front end of the elastic metal sheet 324 is slightly tilted outward in the initial state. After being inserted into the positioning hole 322, the elastic metal sheets 324 on both sides are squeezed, deformed, and contracted to abut against the same side of the inner wall of the positioning hole 322, ensuring the stability of the positioning.

[0026] In some embodiments, the outer wall of the elastic metal sheet 324 is integrally formed with an arc-shaped protrusion in the longitudinal direction; The inner wall of the positioning hole 322 has arc-shaped grooves on the left and right sides corresponding to the arc-shaped protrusions on the same side; The arc-shaped protrusion is inserted into the corresponding arc-shaped slot.

[0027] Specifically in this embodiment, the arc-shaped protrusion and the arc-shaped slot are matched and positioned so that the arc-shaped protrusion on the outer wall of the elastic metal sheet 324 is engaged in the arc-shaped slot on the inner wall of the positioning hole 322. Furthermore, during insertion and withdrawal, the arc-shaped protrusion is compressed, transmitting force to the elastic metal sheet 324. The deformation of the elastic metal sheet 324 allows the arc-shaped protrusion to slide smoothly out of the arc-shaped slot.

[0028] In some embodiments, the detachable limiting and fixing structure 34 includes: The second ear plate 341 is fixedly assembled at the rear edge of the right side face of the shield 31. The second ear plate 341 has a round rod 343 rotatably connected to the middle of the upper, middle and lower positions on the front wall; A rotating handle 344 is fixedly mounted on the front end of the round rod 343; A first strip-shaped through hole 342 is provided at the outer edge of the heat dissipation window 2 corresponding to the rear end of the round rod 343, and the rear end of the round rod 343 passes through the corresponding first strip-shaped through hole 342. A strip-shaped limiting plate 345 is fixedly assembled at the rear end of the round rod 343; The length and width of the strip-shaped limiting plate 345 are both smaller than the length and width of the first strip-shaped through hole 342; When the strip-shaped limiting plate 345 is rotated to be set laterally in the length direction, it blocks the rear side of the corresponding first strip-shaped through hole 342.

[0029] Specifically in this embodiment, gripping the rotating handle 344 can rotate the corresponding round rod 343, thereby driving the strip-shaped limiting plate 345 at the rear end of the round rod 343 to rotate; Furthermore, when the strip-shaped limiting plates 345 at the rear ends of the round rods 343 at the top, middle and bottom are all rotated to be set longitudinally in the length direction, and under the premise that the sliding auxiliary positioning structure 35 on the upper and lower sides is released from positioning, the heat dissipation and dust prevention component 3 can be pulled forward, so that the strip-shaped limiting plate 345 can be pulled out from the corresponding first strip-shaped through hole 342, and the positioning plug can be pulled out from the positioning socket 322 at the same time, and the slider 353 and the horizontal plate 354 that are in contact with positioning can be pulled out from the second strip-shaped through hole 351, thus completing the disassembly of the heat dissipation and dust prevention component 3; More specifically, a strip block is fixed in the middle of the front wall of the rotary handle 344. This strip block can be used as a gripping point. At the same time, the strip block also serves as a reference for the rotation angle of the rotary handle 344. When the strip block is longitudinal, the strip limiting plate 345 rotates to the horizontal setting state in the length direction; when the strip block is horizontal, the strip limiting plate 345 rotates to the longitudinal setting state in the length direction.

[0030] In some embodiments, the sliding auxiliary positioning structure 35 includes: The third ear plate 356 is fixedly assembled to the rear edge of the upper and lower surfaces of the shield 31; The second strip-shaped through hole 351 is opened on the left and right sides of the third ear plate 356; A slider 353 is slidably fitted inside the second through hole 351, and a sliding handle 352 is fixedly fitted at its front end. The outer rear end of the left and right sliders 353 is integrally formed with a horizontal plate 354; A clip 355 is fixedly installed at the edge of the inner wall of the heat dissipation window 2, located outside the second strip-shaped through hole 351. The slider 353 slides outward along the corresponding second strip-shaped through hole 351, and the horizontal plate 354 abuts against the rear end of the same side block 355.

[0031] Specifically in this embodiment, the slider 353 is slid left and right by sliding handle 352, and slider 353 drives horizontal plate 354 to slide laterally along second strip-shaped through hole 351. Furthermore, sliding the slider 353 outward causes the horizontal plate 354 to abut against the rear end of the same-side locking block 355. At this time, the locking block 355 blocks the horizontal plate 354 from moving forward, thus positioning the heat dissipation and dustproof component 3 in a limiting direction. More specifically, slide the sliders 353 on the upper and lower sides inward to the inner end of the corresponding second strip-shaped through hole 351, so that the horizontal plate 354 disengages from the rear end of the corresponding latch block 355. At this time, the sliders 353 and the horizontal plate 354 can be pulled out from the corresponding second strip-shaped through hole 351, provided that the heat dissipation and dustproof component 3 is released from positioning in other directions.

[0032] In some embodiments, the front wall of the sliding handle 352 is uniformly provided with longitudinal grooves along the length direction. The opening of the longitudinal grooves increases the friction of the front wall of the sliding handle 352, making it easier to drive the slider 353 to slide left and right along the second strip-shaped through hole 351 by pushing the front wall of the sliding handle 352.

[0033] In some embodiments, a wind guide baffle structure 4 is fixedly connected to the upper end of the rear wall of the mesh cover 33, and its lower end extends to the lower end of the rear wall of the mesh cover 33. The air guide baffle structure 4 includes: Screw 42 is uniformly fixedly assembled to the upper end of the rear wall of mesh cover 33 along its length; The strip plate 41 has a pre-drilled hole corresponding to the screw 42; After the screw 42 passes through the corresponding reserved hole, it is screwed with an internal threaded sleeve 43. The lower end of the strip plate 41 is bent to form an inclined plate 44, which is inclined toward the side away from the mesh cover 33; The lower end of the inclined plate 44 is bent to form a longitudinal baffle 45, which covers the area below the rear wall of the mesh cover 33. The outer wall of the internal threaded sleeve 43 has anti-slip texture.

[0034] Specifically in this embodiment, the air guide baffle structure 4 plays a guiding role, allowing the airflow to pass more smoothly through the heat dissipation and dustproof net, thereby improving the heat dissipation efficiency. Furthermore, the internal threaded sleeve 43 presses and fixes the strip plate 41 to the upper end of the rear wall of the mesh cover 33. When disassembling, all the internal threaded sleeves 43 are screwed off. No external tools are required for disassembly here. The ease of installation and disassembly can be improved by reasonably reducing the number of internal threaded sleeves 43 and screws 42. More specifically, the inclined plate 44 and the longitudinal baffle 45 form a guide plate to direct the airflow to the filled filter cotton 36; Understandably, the anti-slip texture increases the friction on the outer wall of the internal threaded sleeve 43, making it easier to manually rotate the internal threaded sleeve 43.

[0035] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
